Hi I have problem with Snake Eater, I can't save anything about the game. I tried the Snake vs Monkey and when I go to save it says that it failed to save, then I go to a new game and the same happens when I save, even Para-Medic says there was an error saving. When I check the memory on the PS2 menu a file appears as corrupt and I can't delete it. I tried it with my backup and my original and even tried with an original copy of a friend and got the same thing, and other games save without problems. Can anyone help me? Thanks.
